Velociowl – Generating reports with Velocity

Velociowl (a temporary name) is a plugin for Protégé-OWL, which integrates the Velocity templating tool from the Apache Jakarta project.

With Velocity, you can create a customized report (or any other kind of output), designing a sample of the required output file, and filling it with “variables”. The you will be able to set the variables with any object from the Protégé OWL API.

The result is a very flexible reporting tool.

The plugin doesn't add much to the power of Protégé and Velocity: it simply crates a bridge, and offers a convenient user interface to launch the reports.

The plugin was developed by Massimo Coletti, for Banca Finnat Euramerica S.p.A.


The plugin is currently an alpha non-tested version a2.

Build date: October 11, 2006.
